3M Fire Barrier Mouldable Putty

Transcription

1 3M Technical Data Sheet 3M Fire Barrier The 3M Fire Barrier consists of a synthetic elastomer designed for use as a one part, intumescent fire resistive putty used to restore the integrity of fire rated building construction. achieves up to a 4 hour Fire Resistance Rating when tested in accordance with AS & AS This is achieved by the unique intumescent (expanding when heated) and high strength insulating char-forming properties of this material. Product Features Halogen-free formula: Free from corrosive gases during a fire, making it safe for building occupants and sensitive electrical equipment. Minimal odour Long shelf life: Sticks and pad packages can be sealed for reuse. Putty will not dry out or crumble Easily re-enterable Provides a draft and cold smoke seal in the installed condition, even before any temperature rise occurs, resulting from a fire Adheres to all common building surfaces (cement, gypsum, wood and plastic), including metal and plastic electrical boxes One part, solventless pads or Sticks are easily hand moulded, with no damming required, allowing easy application Intumescent: expands when heated, forming a hard char, preventing the transmission of hot gases and fire No special tools required Contains no asbestos, non toxic Testing in accordance with AS1530.4, AS4072.1, EN1366, and ASTM E814 (UL Listed).

3 Performance Specifications for Installers 3 Table 1 3M Fire Barrier System 3M Fire Barrier Building Element Floor: Concrete slab. Minimum 120mm thickness Wall: Plasterboard Dry Wall, solid masonry, hollow masonry or concrete construction. Minimum 116mm thickness Wall: Solid masonry, hollow masonry or concrete construction. Minimum 150mm thickness Blank (Unpenetrated) Seal Mixed PVC Insulated Cables, Cable trays and Cable bundles * -/240/120 -/180/- -/240/30 -/120/120 -/120/30 -/120/30 -/240/180 -/120/30 -/120/30 For Telecommunication Cables, Cable trays and Cable bundles only * In order to achieve the above FRLs you must ensure that the is installed as per the Installation Techniques and the building element you are installing into has an FRL performance equal to or better than that of the system. The Installation Techniques can be found on the final pages of this document. What does FRL mean? FRL stands for Fire Resistance Level. For example, an FRL of -/240/180 indicates: Structural Adequacy. The first dash - indicates that is non load bearing Integrity. The middle number 240 indicates for how many minutes the system can resist the passage of flames and hot gasses Insulation. The last number 180 indicates how many minutes it takes the unexposed face to heat up by more than 140 o C. *Where the FRL of the firestopping system requires an insulation value greater than that given in table 1, the use of additional insulating wraps can be employed - see Appendix A.

4 Performance Specifications for Engineers and Specifiers 3M Fire Barrier has been tested in accordance with AS and assessed in accordance with AS The following illustrations provide a summary of the test results for D1 and D2 cable configurations and blank unpenetrated seals with installed as per the Installation Techniques. Specifications for standard D1 and D2 cable configurations can be found in AS Appendix D. 4 D1 Cable Pack Power Transmission Cables. + 20mm deep + 20mm deep + 40mm deep Dry Wall 116mm FRL: -/180/30 Solid Masonry, Hollow Masonry or Concrete Wall 116mm FRL: -/180/30 Concrete Floor 120mm FRL: -/180/- D2 Cable Pack Telecom Cables. + 20mm deep + 20mm deep + 40mm deep Dry Wall 116mm FRL: - /120/30 Solid Masonry, Hollow Masonry or Concrete Wall 116mm FRL: -/120/30 Concrete Floor 120mm FRL: -/240/30 Blank Openings (unpenetrated) + 25mm deep + 25mm deep + 40mm deep Dry Wall 116mm FRL: -/120/120 Solid Masonry, Hollow Masonry or Concrete Wall : 116mm - FRL: -/120/ mm - FRL: -/240/ mm - FRL: -/240/240 Concrete Floor : 120mm - FRL: -/240/ mm - FRL: -/240/ mm - FRL: -/240/240

Ensure that enough space is left on either side of the mineral wool for the. Install to a depth of 20mm for electrical cables and 25mm for blank unpenetrated seals on both sides of the wall. It is usually easiest to mould the Putty into place one section at a time. Ensure that the Mouldable Putty is installed flush with the wall on both sides of the penetration. Wrap cables and metal pipes with a single layer of 3M Fire Barrier + Pad for the full depth of the seal. 5 Installation Techniques: Floors + 40mm deep + 40mm deep Electrical Cables, Blank (unpenetrated) Seals Install mineral wool infill friction fitted into the floor slab, the bottom of the mineral wool should be flush with the bottom surface of the floor slab. Ensure that enough space is left above the mineral wool for the. Install to a depth of 40mm on the top side of the floor slab only.
